BJJ or Muay Thai?

I just started P90-X about 3 weeks ago (man, it is INTENSE) and have been seeing great results already - highly recommend it for anyone looking for an at home work-out.

Anyway, I've decided that it's not enough and I'm looking at getting into martial arts. Just wondering if anyone here does Brazilian Jiu-Jitsu or Muay Thai? I'm thinking about these two specifically as I feel it would be a good base for getting into MMA. I'll most likely start both, but what else should I consider?

Ring fighting, definitely... although, I do seem to get myself into a number of situations where having some training would be beneficial :D

I can see your point, but the way I see it is: you can go through life worrying about every aspect of your health, or you can live it how you want and have fun. Everything these days is "unhealthy" - just walking outside. It's all about weighing the risks and benefits.

As with a lot of sports, whether it be hockey, football or MMA, it's going to take a toll on your body. In the end though, as long as you enjoy doing it, then I think it's worth it.

Have you tried Insanity beachbody? Its a great hard home workout (but i do prefer punching something solid instead of the air!)

When it comes to martial arts I have done some Muay Thai but for the most part kickboxing & boxing (with some ring sparring) for the past 15 years.
I haven't done BJJ but I highly recommend Muay Thai. I just copied this off an interesting site...

Muay Thai Philosophy - Train the body, mind, and heart. Physical conditioning is useless without developing concentration and dedication. Show patience and persistence with yourself and others. Develop speed as well as Muay Thai techniques. Show respect for your parents, teachers, community, and yourself. Be honest and courteous, and help others when you have an opportunity. Approach all situations with diligence and self-confidence. Contribute to unity and spirit of the Muay Thai brotherhood. Use common sense and intelligence when in a bad situation. Practicing good Muay Thai means resorting to fighting only as a last resort.

Benefits of Muay Thai

Muay Thai is many things turned into one. Namely, self-defence, sport, science, and art. Over the years it has enriched our physical and moral well-being, as well as fame, honour, and wealth. In the past, Thai boxers were often under the patronage of the kings. Some boxers even rose to become the ruling monarchs of the land. Skilful boxers of the bygone era were often recruited to be some kind of the King's 'special soldiers' acting as the bodyguards of the kings. The name of Muay Thai itself has travelled far and wide, causing fear in the hearts of opponents. It has proved itself against various forms of martial arts such as Karate, Judo, Kung Fu, Jujitsu, Wrestling, or indigenous boxing of other countries.

Muay Thai has demonstrated to the world its effectiveness. Many martial arts are now incorporating Muay Thai techniques into their systems. Muay Thai is full of colourful and effective techniques. Advanced training in weapons is available, but not necessary for most. There are many benefits to training in Muay Thai aside from the obvious self-defence application. As your physical strength, coordination, and stamina develop, you will also notice improvements in your determination, patience, and self-control. The goal of Muay Thai training is the development of the whole self. The benefits that a person would receive from Muay Thai include the following:

Physical Benefits:
A Well-Proportioned Body - Before any competition or training, one should warm up lightly or get massaged. The massage of the muscles improves blood circulation. The training speeds up the body's metabolism and burns off fat. Eventually, you will notice a decrease in fat, an increase in muscle, and an overall improved sense of well being.
Strength and Agility - Regular training will build up your stamina and put your body in good shape. You should be able to withstand being hit by various weapons of the opponent. Your pain tolerance should be higher. The body will get used to arduous routines and becomes stronger as a result. The constant training and drilling in Muay Thai techniques will allow your mind and body to instantly and effectively react to your opponent’s attacks.
Resistance to Illness - As Muay Thai requires movement of every part of the body, the practitioner will be very fit and strong. Good health would lead to better resistance to illness or diseases. If the body is in good shape, you will not suffer from any illness.

Mental Benefits:
Courage, Determination, and Self-Confidence - Regular exercises are very important in Muay Thai. The body will be driven to the limit of exhaustion. If you do not have stamina and determination, you will certainly give up, so it is necessary to train the mind to be tough. In Muay Thai or any kind of profession, a good player in the game must have supreme self-confidence that one could successfully complete various manoeuvres to make timely and sudden decisions. This quick thinking is crucial to a hand to hand combat like Muay Thai. To be a top class Muay Thai fighter, one will have to undergo the training to instil self-confidence and ability to make decisive decisions.

Intelligence and Wisdom - Muay Thai is a self-defence that is full of tactics, tricks, and techniques. Training in Muay Thai means learning all the tactics to defeat the opponent and the ways to counter your opponent's manoeuvres. A Muay Thai practitioner must have enough wisdom in using the techniques and tricks, supported by a fair degree of intelligence.
Discipline and Good Spirit - To be successful in the art of Muay Thai, one must be well disciplined and obedient to the teacher's instructions. Furthermore, one should attend the training sessions regularly, look after one's health, and adhere to the pattern of training.

Social Benefits:
The proper maintenance of health will compliment the martial tactics acquired. In normal circumstances, a Muay Thai practitioner will be indoctrinated on the subject of discipline, respect for the rules of the school, and obedience to the instructor. This will lead to the possession of good manners, good spirit, honesty, sense of justice, and self-confidence.
